A stacking apparatus and a method for assembly of electrochemical cells. In one embodiment, the substrate comprises a dielectric substrate formed within a board, for example, a printed circuit board. An image is corresponding to the visual information transmitted through the electro-mechanical actuator module. Each portlet can be manually placed into or out of a locked state. The method includes the steps of downloading and displaying a media element in the linear program and responding to user commands to download and display the next media element in the linear program.
